Expression study of human embryonic stem cells, dental pulp cells (DPCs) and induced pluripotent stem cells (iPSC) obtained from DPC for characterization of iPSC

ABSTRACT: iPSC were obtained from DPC from TRPC6-mut patient, a idiopathic autistic patient and a control. Original DPC and iPSC obtained were submited to expression analysis in order to check if the expression pattern obtained for the iPSC cells were closer related to embyonic cells than to the original DPC DPCs were grown until reach 80-90% of confluency in DMEM/F12 media supplemented with 15% fetal bovine serum (Hyclone, TX), 1% penicillin/streptomycin, and 1% non-essential amino acids and maintained under standard conditions (37°C, 5% CO2). RNA samples were extracted from cells in passage 5 to 7. iPSC were grown until reaches 70% of confluency in mTSER medium (Stem Cells Technologies). RNA samples were extracted from cells in passage 12 to 15.

Expression study between dental pulp cells from TRPC6-mut individual and control individuals

Project description:As TRPC6 channel induces CREB-mediated trancription, Dental pulp cells from TRPC6-mut patient and from 6 controls were analyzed in order to verify if the disruption of TRPC6 leads to transcriptional changes. Cells were grown until reach 80-90% of confluency in DMEM/F12 media supplemented with 15% fetal bovine serum (Hyclone, TX), 1% penicillin/streptomycin, and 1% non-essential amino acids and maintained under standard conditions (37°C, 5% CO2).

Affect of iPSC Passage Number on Neuronal Differentiation

Project description:Induced pluripotent stem cells (iPSCs) are a valuable resource for neurological disease-modeling and drug discovery, due to their ability to differentiate into neurons reflecting the genetics of the patient from which they are derived. iPSC-derived cultures, however, are highly variable due to differences in culture conditions. We investigated the effect of iPSC passage number on differentiation to optimize the generation of functional, mature sensory neurons (iPSC-dSNs). Three iPSC lines were differentiated into iPSC-dSNs at passage numbers within each of the following ranges: low (LP; 5-10), middle (MP; 20-26), and high (HP; 30-38). Morphology and pluripotency of the parent iPSCs were assessed prior to differentiation at each passage number. iPSC-dSNs were evaluated based on electrophysiological properties and expression of key neuronal markers. All iPSC lines displayed the same morphology and were similarly pluripotent across passage numbers. iPSC-dSNs were also morphologically comparable across passage numbers. However, the expression levels of neuronal markers and an analysis of sodium channel function indicated greater maturity in LP iPSC-dSNs. Our results demonstrate that lower passage numbers may be better suited for differentiation into peripheral sensory neurons. Further studies are warranted to elucidate factors that may contribute to the variability associated with iPSC passage number.

Genome-wide analysis of PARKIN deficient patient fibroblast and iPSC lines

Project description:Analysis of whole genome gene expression in control and PARKIN patient lines. The hypothesis tested in the present study was that the deficient of PARKIN expression affects multiple pathways. Results provide important information on relationship between PARKIN and mitochondria related gene expression. Total RNA obtained from patient fibroblast and iPSC compare to control fibroblast and iPSC.
